Why are "cornflowerblue" and "cornflower blue" different colors?

There are several places in racket/draw/private/color.rkt where two names differ by a space, but are defined as the same color. However, "cornflowerblue" and "cornflower blue" seem to break this pattern. Is there a reason why they are different?

Definition of "cornflowerblue":
https://github.com/racket/draw/blob/master/draw-lib/racket/draw/private/color.rkt#L143

 ("cornflowerblue" . #(100 149 237))

Definition of "cornflower blue":
https://github.com/racket/draw/blob/master/draw-lib/racket/draw/private/color.rkt#L249

 ("cornflower blue" . #(68 64 108))

It looks like "cornflowerblue" without the space has the same RGB values as the X11 cornflower blue on https://en.wikipedia.org/wiki/Cornflower_blue, so where do the RGB values for "cornflower blue" with the space come from? Is it a mistake or intentional?

Read the two color definitions in racket/draw/private/color.rkt at the referenced entries and compare their RGB values and naming patterns. Check the surrounding definitions and relevant project history to determine whether the difference is intentional or erroneous. Done means establishing the source of the spaced name's values and resolving the discrepancy or documenting its reason.
